Page 1
DESCRIPTION:
Kingston's KHX8500D2K2/4G is a kit of two 256M x 64-bit 2GB (2048MB) DDR2-1066 CL5
SDRAM (Synchronous DRAM) memory modules, based on sixteen 128M x 8-bit DDR2 FBGA
components per module. Total kit capacity is 4GB (4096MB). Each module pair has been tested to
run at DDR2- 1066MHz at a latency timing of 5-5-5-15 at 2.2V. The SPD is programmed to JEDEC
standard latency 800Mhz timing of 5-5-5-18 at 1.8V. Each 240-pin DIMM uses gold contact fingers
and requires +1.8V. The electrical and mechanical specifications are as follows:
FEATURES:
Power supply : Vdd: 1.8V ± 0.1V, Vddq: 1.8V ± 0.1V
Double-data-rate architecture; two data transfers per clock cycle
Bidirectional data strobe(DQS)
Differential clock inputs(CK and CK)
DLL aligns DQ and DQS transition with CK transition
Programmable Read latency 5 (clock)
Burst Length: 4, 8 (Interleave/nibble sequential)
Programmable Burst type (sequential & interleave)
Timing Reference: 5-5-5-18 at +1.8V / 5-5-5-15 at +2.2V
Edge aligned data output, center aligned data input
Auto & Self refresh, 7.8us refresh interval (8K/64ms refresh)
Serial presence detect with EEPROM
High Performance Heat Spreader
PCB : Height 1.180” (30.00mm), double sided component
PERFORMANCE:
Clock Cycle Time (tCK) CL=5 2.5ns (min.) / 8ns (max.)
Row Cycle Time (tRC) 51.5ns (min.)
Refresh to Active/Refresh Command Time (tRFC) 127.5ns
Row Active Time (tRAS) 39ns (min.) / 70,000ns (max.)
Single Power Supply of +1.8V (+/- .1V)
Power 1.584 W (operating per module)

MODULE DIMENSIONS:
All Kingston products are tested to meet our published specifications. Some motherboards or system configurations may not
operate at the published HyperX memory speeds and timing settings. Kingston does not recommend that any user attempt to
run their computers faster than the published speed. Overclocking or modifying your system timing may result in damage to
computer components.
